WILLIAM H. GOODMAN, OE PALMYBA, VIRGINIA.

HARROW.

SPECIFICATION forming part of Letters Patent N0. 320,347, dated June 16, 1885.

Application filed September 3, 1884.

T0 aZZ whom it may concern.-

Be it known that I, \V-ILLIAM HENRY Goon- MAN, a citizen of the United States, residing at Palmyra, in the county of Fluvanna and State of Virginia, have invented certain new and useful Improvements in Harrows, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of this improvement is a harrow of simple, economical construction and operation, with parts that will adjust themselves to the unevenness of the ground over which it moves, and that may be rigidly connected, in order that the harrow may be weighted, andthus made to penetrate and stir the soil to a greater depth, as occasion may require. These results are attained by the mechanism illustrated in the drawings herewith filed as part hereof, in which the same letters of reference denote the same parts in the different views.

Figure 1 isa plan. Fig. 2isaside elevation.

A A are partially-twisted metal plates, suitably secured to a draft-pole, B, transverselybraced by a plate, A, and provided at their rear ends with integral eyes a. .B is a metal plate secured to the draft-pole B and transverse plate A' and provided with an eye at its rear end for the insertion of a rod, D, which passes through the eyes a, and completes the formation of the draft-frame, to which it is secured by means of the nut d. The rod D passes through correspondingly-sized perforations in the forward ends of the dragbeams E, which are provided with harrow-teeth G of ordinary construction. The beams E are provided on their upper surface with suitably-connected vertical pins H, which fit loosely through perforations or slots in a bar, I, which extends entirely across the rearward part of the implement and holds the beams E apart from each other, as shown, their relative positions being secured at their forward ends by intermediate washers, I on the rod (No model.)

D. The beams E are provided at their rear ends with correspondingly-located perforations for the reception of a rod, K, which is to be inserted therein for rigidly connecting the beams E, and thereby adapting the implement to be weighted and the harrow-teeth l thus made to sink deeper into the soil, as oocasion may require. Pivotally secured to each side of the draft-frame is a plate, 0, having integral eyes a, and provided with rollers C, i which support the forward part of the harrow, and facilitate the tu rning of the same. By providing the rear ends of the beams E with vertical pins, as shown at H, and a transverse I bar similar to I, slotted longitudinally with 1 the machine to be set over said pins, the beams E may be thereby held apart at their rear ends. When the rod K is removed from the beams E, they will oscillate independently of each other on the rod D, and automatically adjust themselves to the surface of the ground over which they move. By disconnecting the rod D from the draft-frame, and removing the part B, a roller may be readily attached and a convenient mechanism for pulverizing the clods thus provided.

Having explained the construction and operation of my improvemen, what I claim as new, and desire to secure by Letters Patent, is

In a drag-barrow, the combination, with the draft-frame formed of the plates A A A having eyes a, the tongue B, and rod D, of the perforated plate I, and the dragbeams E, provided with pins H, and having perforations in their rear ends adapted to receive the removable rod K, whereby the beams may be rigidly connected and weighted, substantially as described.
